WEATHER-STRIP.

SPECIFICATION forming part of Letters Patent No. 305,471, datedSeptember 23, 1884.

Application filed May 28, 1884. (No model.)

To all whom it may concern:

Be it known that I, EMMELINE W. PHIL- BROOK, of Boston, in the county ofSuffolk and State of Massachusetts, have invented a new and usefulImprovement in a Combined feather-Strip and WVindow-Lock, whichimprovement is fully set forth in the following specification.

'The object of this invention is to provide a device or attachment to beapplied to the windows of houses, railway-cars, 850., whereby air may beprevented from entering between the meeting-rails of the sashes andwhereby, also,

the window may be locked in any positioneither closed or more or lessopen.

It is often desirable to leave awindow slightly open at night for thepurpose of ventilation,

but with the window-locks in general use this necessitates leaving thewindow unfastened. \Vith the locking attachment'herein described thewindow is secured in any position and cannot be opened farther from theoutside. The device is also useful for railway-cars, the windows ofwhich are usually so contrived as to be fastened only in two or threepositions,

and 'if raised but slightly are liable to fall by reason of the jar ofthe train.

In carrying out the invention a thin strip of wood as long as-the widthof the sash is hinged at its outer edge to the top rail of the lowersash. From its inner edge projects a strip of stiff IIIbbGl OlOth orsimilar material, extending to the glass of the upper sash. By thisdevice the space between the two rails is closed to the passage of air,whether the window be open or closed. At one end of the strip is afastening devicesuch as a spring catch or pawl-which, when the strip isfiat upon the rail, (in which position it is or may be normally held bya spring,) engages a cor responding device on the upper sash-frame. Toraise the window, the strip is turned 011 its hinges, disengaging thefastening devices. When released, the spring restores the strip to itsnormal position.

The device is particularly advantageous for use in connection with aventilating windowscreen-such as introduced into the windowframe aboveor below the sashsince it looks the sash against the frame of thescreen, andwindowsash.

compels all the air entering the room to come through the wire-gauzescreen.

The accompanying drawings, which form a part of this specification,illustrate a window attachment constructed in accordance with theinvention, Figure 1 being a front elevation,

Fig. 2 a cross-section on line at .r, and Fig. 3 a

partial vertical section.

B represents a thin strip of wood secured by hinges b to the top rail,A, of the lower From the inner edge of strip 13 projects theweather-strip a, of rather stiff rubber-cloth, felt, or similarmaterial, entirely filling up the space between the rail Aandthe glassof the upper sash, O. The ends of strip a are cut to fit the molding ofthe upper sashl frame.

The strip B carries at one end a spring catch or pawl, d, which normallyengages one of the teeth of the rack-bar D, fastened by screws orotherwise to upper sash-frame.

When the strip B is in its normal position,

the engagement of these devices effectually prevents the opening of thewindow either at top or bottom.

The action of the weather-strip and loclzing 1 strip 13 it immediatelyresumes its normal position under the influence of spring E, and thecatch or pawl d engages one of the teeth of bar D, automatically lockingthe window at that point. Since the strip. a extends to the pane ofglass of the upper sash, it acts to exclude the air at that point whenthe window 7 is open as well as when closed. This is specially desirablewhen the device is used in connection with a window-screen ventilator,such as described in Letters Patent No. 286, 555, granted to me October9, 1883. When such device is inserted in the window-frame, the sashbeing sufficiently raised (or lowered) to admit it, there wouldordinarily be a considerable opening between the glass of one sash andthe rail of the other through whichquantities of dust and insects canpass, thus to a certain extent defeating the purposes of the screen.this objection is removed, and all the air entering the apartment mustpass through the wire-gauze of the screen.

The locking device described, besides possessing the advantages ofautomatic action and of securing the window in an open as well as aclosed position, is much more efficient than the devices ordinarilyapplied to the meet-ingrails of sashes, which, as commonly constructed,can be pushed aside by inserting a knife-blade between the twosash-rails. In the present case the crack between the rails iseffectually closed by the weather-strip, which itself is locked by thedevices D d as well as the window.

Where the sash has two panes or more, the

strip a must be cut to fit the vertical divisions of the sash, and wherethe sash is divided horizontally as well, the strip B must be turned"011 its hinges enough to clear the part a of such divisions on raisingthe window to its full height. v

If it is desired that the lock shall prevent the closing as well as theopening of the window, (as in case it is applied to the car-windows,)the teeth of bar D would of course be made with two straight faces toengage the catch or pawl d on both sides, V

The strip B would preferably be made of the same material and finish asthe window-frame, since it may be made apermanentpart thereof, beinguseful in all seasons.

It is obvious that parts of the invention may be used separatelyforexample, the windowlock without the weather-stripand that modi ficationsin details of construction may be made without departing from the spiritof the invention.

By the present invention, however,

Having now fully described the saidinvention and the manner of carryingthe same into effect, what I claim is- 1. The combination, with themeeting-rails, of the weather-strip and locking device for locking thewindow in either an open or closed position, substantially as described.

2. The combination, with the meeting-rails, of the hinged weather-stripand the spring bearing upon the latter, substantially as described. v

3. The combination, with the meeting-rails, of the weather-strip hingedto one of the' rails and extending to the glass of the other sash, andthe locking devices, substantially as described.

4. The combination of the hinged weatherstrip and the automatic lockingdevice, substantially as described.

5. The combination of the weather-strip,

the spring catch or pawl carried thereby, and the rack-bar on thesash-frame, whereby the window may be locked either open or closed andthe strip simultaneously locked'in place, substantially as described.

6. The combination of the hinged strip, the locking devices, and thespring acting to throw said devices into engagement.

7. The combination of the sash-frames, weather-strip hinged to-one ofthe meetingrails, spring acting on said strip, spring catch or pawlcarried by said strip, and rack-bar on the'sash-frame, all constructedand operating substantially as described.

In testimony whereof I have signed this" specification in the presenceof two subscribing witnesses.
